To all whom, it may concern:

Be'it-known that I, M'An'rrNFEYBUsoH, a

citizen of the German Empire,' and a resident of Sea Cliff, in thecounty of Nassau and. State of New York, haveinvented certain new anduseful Improvementsin Machines .for Goatin Labels and Similar Ar ticleswith Adhesive, of which the followin is a specification.

his invention relates to a machine of novel construction for providingthe backs of labelsand similar articles with an adhesive coating so'thatthe labels are ready for attachment to their bases by means'ofadditional machines, with which the ma.- chine which forms the subjectmatter of the present invention, is designed to cooperate. The machineis also applicable to blanks that go to form paper boxes or partsthereof, and to various other articles which are to be covered by anadhesive on one of their sides.

Briefly stated, the labels to be coated are stacked within an adjustablemagazine, their forward edges being brought into engagement with arubber-covered roller,

. which is fixed. This roller serves'not as a conveyer, but as anabutment, against which the labels are feathered out by meansof a seriesof feed tapes that constitute the bot- 'tom of' the magazine. ,Thesefeed tapes carry the successive bottom labels from under the fixedroller, and thus out of the magazine, to be engaged by a second seriesof feed tapes which are operable either in conjunction with orindependently of the first series. The second series of tapes in turnconveys the labels beneath a pair of conveying rollers and under atension blade to a paste applying roller, to the periphery of which theyare held so as to become coated in the manner desired. The coatedlabelsare stripped off this roller by a number of pick ofi's which turn thelabels over and conduct them, bottom upward, upon a conveyer belt. Onthis belt, they are subjected to the action of a number of pressure de-.eeling, and.

. the specification and appended claims.

as v

Fig. 2, a right hand side elevation;

gummed- This magazine is formed of a pair of side plates 3, mounted on atransverse shaft 4, along which they are adjustable so that the magazinemay be set to labels of different widths. The bottom'of the magered byrubber jacket 11 and constitutes a cylindrical abutment for the labels.The shaft of this roller engages slotted arms 12 of the machine frame,along which it may be vertically adjusted by coned screws 13, so that inthis way, the clearance between the roller and the feed tapes may be setto labels of different thicknesses. In order to adapt the magazine forthe reception of labels which are longer than tape 5, frame 1, isprovided with a rearwardly extending longitudinally adjustable bracket14: in whi'c is mounted, a vertically adjustable shaft 15. On this shaftare mounted, a plurality of laterally adjustable clamps 16, carryingfingers v 17,. the front ends of which are adapted to rest "upon one ofthe idlers 8 intermediate tapes 5, while their rear ends extend aconsiderable distance back of frame 1. \Vhen a pile'of labels is placedupon the fingers, it will, by the forward portions of the feed tapes, becarried against the fixed cylindrical abutment 10 by means of which thelabel .are, feathered out, insuch a manner that the forward edge of thepile is concaved and that the bottom label only will be fed out of themagazine by the feed tapes. The latter convey the label thus withdrawnfrom the magazine, upon a second set of parallel belt or feed tapes 18-that advance it on its way toward the adhesive-receiving meanshereinafter referred to.

Tapes 18 pass over front feed roll 19 and a rear feed roll 20, thelatter being spaced a short distance beyond front roll 6, of the firstset of tapes 5. Between rolls 19, 20 there are arranged, a number ofidlers 21, one of which is flanged as at 22, while above the tapes aremounted in the machine frame a number of pressure rolls 23, that serveto hold the labels to the tapes, during their travel along the latter.The object of providing two independent sets of feed tapes, is to permiteither both sets. to be operated simultaneously (which is the normalcondition) or the advance set 18 to be driven, while the rear set 5 isat rest. This stopping of the rear tapes should take place when themagazine is empty in order to then prevent an abrasion of the rubberjacket 11 by the moving tapes 5 while the continued motion of the fronttapes, will carry the train of labels last released to the gummingmechanism.

The means for driving the tapes are shown to be as follows: Power shaft24 by coned pulley 25, belt 26, and coned pulley 27, drives acountershaft 28. The latter, by pulley 29 and belt 30 drives a disk or ulley31, that may be coupled to the main drive shaft 32 by a clutch 33 (Figs.1( )12). The clutch may be opened or closed from thefront of the machineby a handle34 (Fig. fast on an upright rock shaft 35 having a finger 36,that engages a groove 37 in the hub of clutch 33.

Shaft 32 by chain drive 38, turns a stub I shaft 39 having a long gearwheel 40, in

which meshes a pinion 41 fast on feed roll 20 and also a pinion 42 of aclutch 43 (Figs. 6-8) adapted to be coupled to feed roll 6. Clutch 43 isoperated from a rock shaft 44 by link 45, connecting rod 46, link 47,upright shaft 48 and finger 49, so that when the clutch is thrown in,both sets of feed tapes are operated by pinions 41, 42 while when theclutch is thrown out by the turning of shaft 44, the front set only isoperated by pinion 41.

Rock shaft 44 is also axially slidable and at 53, integeared with shaft32.

stop the rear feed only, while' by sliding it he may stop the entiremachine.

The front feed tapes 18 carry the labels toward and between a pair ofintergeared feed roll 51, 52 the lower one of which is From rolls 51, 52the label passes underneath the lower edge of a tension blade 54 thatserves to deflect thelabel toward the face of an adhesive applyingroller 55, which is vertically adjustable and contacts witha pastereceiving roller 56 dipping into a pan or receiver.57 containing anadhesive, such glue. or paste. Roller 56 i at 58 intergeared with feedroll 52 and is in turn at 59, intergeared with paste applying roller 55,,so that rollers 55 and 56 turn in opposite directions.

To the front of the machine, there is fulcrumed at 60, a bracket 61 inwhich is journaled, a shaft 62 intergeared at 63 with roller 55 andarranged, a slight distance abovethe same so as tohold the labelsagainst the latter. Over shaft 62, passes an endless conveyer belt 64 towhich the labels are transferred with their backs up from roller 55 bymeans of a number of pick-offs or strippers 65. The latter are securedto arms 67 that turn on a shaft 66 hung inbracket 61 in advance of shaft62 and are made in the form of concaved jaws which strip the labels ofl'roller 55 after having remained in contact therewith for some time andturn them upward and backward in substantial concentricity to theperiphery of shaft 62 which thev partly encompass at the turn of theconveyer belt. The conveyer belt 64 passes from shaft 62 over idlers 68,69, 70, idler 69 being located at such a distance back of the machine asto carry the procession of gummed labels to the labeling" or othermachine with which the presentv machine is designed to coiiperate.

Bracket 61 carries above the upper run of belt 64, a number of shafts 71from which depend hangers 72, in which are journaled pressure rolls ordisks 73. Hangers 72 are longitudinally adjustable along their shafts,so that the pressure rolls may beset over the labels as the latter arecarried out of the machine, and prevent the same from peeling off theconveyer.

By slacking a pair of clamp screws 74 bracket 61 together with itsrollers and other adjuncts may be swung into a horizontal position(dottedlines Fig.1) so as to carry pick-ofi's 65 away from roller 55,and permit all the parts to be readily inspected, re moved, cleaned orrepaired.

The operation of the machine will be readily apparent from the foregoingdescription.

A stack of labels is placed in the magazine, and by the operation of therear feed tapes such stack is forced against the rubber jacket 11 of thefixed roll which thus constitutes an abutment by means of which thelabels are feathered out. The successive lowermost labels aretransferred by the rear tapes 5, to the front tapes 18, which in turnconvey them, beneath blade 54, to the face of the paste applying roller55 that covers their backs with the adhesive. Pick-offs 65 then stripthe labels ofl roller 55, and turn them toward shaft 62, so that in thisway,

, the labels are reversed and are transferred back upward to theconveyer 64. The latter carries the labels to the labeling, box,

making or other machine for further treatment.

The machine is readily adjustable to labels of various dimensions andconfiguration, feathers them out neatly, and carries them in a uniformprocession to the paste applying means and thence to the conveyer.Should the operator of the machine with which the present machine isintended to coiiperate, see that the magazine is empty,he throws outclutch 43, by means of rock shaft "44,

which is within his reach, and thus arrests the rear feed tapes whilethe remainder of the machine retainsits motion, so that the labels thathave left the magazine will continue their travel toward the pasteapplying device and thence to the conveyer belt that keeps on moving andcarries them to their destination.
